Utopian sci fi is popular in literature, but rarely in movies or shows. We’ll get a series about the Culture one of these days though. Special Circumstances can get up to things that puts turning into a lizard and raising babies with your captain to shame.

Edit: I also think some more of Kim Stanley Robinson’s books will get turned into series someday. They’re generally about the progress to a Utopia. Years of Rice and Salt is particularly interesting because it tracks that progress all the way from the dark ages to a Utopia while the characters keep reincarnating and making the same exact mistakes over and over.
